What is the best thermal insulation for roofs?

You can find many options for building the roof of a house, and each of them will have particular characteristics, from its construction to aesthetics. However, not everyone is able to prevent high temperatures from invading the environment, so the ideal is to get to know each other and What is the best thermal insulation for roofs.

Thermal insulators have numerous advantages for those who install them in their home. Among these stands out the improvement of energy efficiencyas spending on heating and air conditioning will be reduced, and the greater comfort inside the homeas temperatures will drop significantly.

This way you can also avoid it drastic changes in temperature that you hear coming home from the street. Additionally, they also work to reduce external sounds.

It should be borne in mind that each type of thermal insulator for roofs it is created specifically to cover certain needs, so they will be better depending on the material the house is made of. Furthermore, there are some characteristics that must be satisfied in their development to have better performance.

Among these it must have: low thermal conductivity, high thermal resistance (ability to resist heat flow), resistance to the passage of water vapor, good behavior against fire and good sound insulation.

What is the best thermal insulation for roofs?

Polyethylene foam. It is an easy-to-install plastic material, which is usually sold in roll format from 5 to 10 mm thick, wrapped in an aluminum box. To use it you must first place a layer of aluminum facing upwards, so that the heat passing through it is reflected there.

Thanks to its materials, it is an alternative that can last a long time. His panels are easy to installthey are also made with water-repellent materials, so they will also prevent the passage of moisture.

In this sense, fiberglass or rock is also one of the most chosen for insulating the heat of the roof. It is made with a mineral fiber created with glass filaments joined with a binder, which also allows insulation from temperature and external noise.

They are usually obtained in rolls of 25 and 100 mm thickness, it is advisable to choose those that have the aluminum face incorporated, since this will avoid the steam condensation. Furthermore, being a reusable material, it is ideal for sheet metal roofing.

He Expanded polystyreneor better known as Polystyrene is a cellular plastic with a spongy shape, generally composed of 98% air and 1 cm thick, very durable and resistant.

However, one of the options most recommended by specialists is polyurethane foam or polyurethane foam. It is generally found in the form of a spray, which quickly turns into a heat-insulating foam. They are found in sheets with an aluminum face, and are also ideal for sheet metal roofing.

There are also other alternatives, such as lightweight felt without aluminium (it is used as a thermal and acoustic insulator and can be placed on sloped ceilings, false ceilings, sloped and unloaded ceilings) and sheet metal roofing paint (water-repellent liquid membrane that helps to reduce the passage of external temperature to the inside).

The choice will depend exclusively on the needs of the person, since all of these fulfill their function perfectly thermal insulation for roofs.
